C3P0连接MySQL8.0.11配置问题

C3P0连接MySQL有两种方式
第一种： 相关参数 在程序中指定user url password

   @Test
    public void testc3p0_01() throws Exception {
        //1.创建一个数据源对象
        ComboPooledDataSource comboPooledDataSource = new ComboPooledDataSource();
        //2.通过配置文件mysql.properties
        Properties properties = new Properties();
        properties.load(new FileInputStream("src\\mysql.properties"));
        String user = properties.getProperty("user");
        String password = properties.getProperty("password");
        String url = properties.getProperty("url");
        String driver = properties.getProperty("driver");
        //给数据源comboPooledDataSource设置相关的参数
        //连接的管理是由comboPooledDataSource管理的
        comboPooledDataSource.setDriverClass(driver);
        comboPooledDataSource.setJdbcUrl(url);
        comboPooledDataSource.setUser(user);
        comboPooledDataSource.setPassword(password);
        //连接数初始化
        comboPooledDataSource.setInitialPoolSize(10);
        //最大连接数
        comboPooledDataSource.setMaxPoolSize(50);

        Connection connection = comboPooledDataSource.getConnection();//这个方法就是从DataSource接口实现的
        System.out.println("连接成功");
    }

第二种方式

public void testc3p0_02() throws SQLException {
        ComboPooledDataSource comboPooledDataSource = new ComboPooledDataSource("hsp_edu");
        Connection connection = comboPooledDataSource.getConnection();
        System.out.println("连接成功");
        connection.close();
    }

配置文件c3p0-config.xml 要区别于老的版本

<!--驱动-->
<property name="driverClass">com.mysql.cj.jdbc.Driver</property>
  <!-- url-->
  	<property name="jdbcUrl">jdbc:mysql://localhost:3306/db02?useSSL=false&amp;serverTimezone=UTC&amp;characterEncoding=utf-8&amp;autoReconnect=true</property>
